  1. 1. Direct and endothelium-linked serotonergic control of vascular tone in human uterine and umbilical arteries

    Författare :Caroline Karlsson; gynekologisk och prenatal ultraljudsdiagnostik Obstetrisk; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; andrology; gynaecology; Obstetrics; vascular smooth muscle; uterine artery human ; umbilical artery human ; serotonergic receptor; 5-HT; noradrenaline; endothelium; NPY; reproduction; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet;

    Sammanfattning : The serotonergic vascular control was investigated by in vitro pharmacology in the human uterine and umbilical arteries. The localisation of immunoreactive (IR) neuropeptide Y (NPY) and the influence of NPY on the adrenergic vascular effects in the human uterine artery were also studied. LÄS MER

  3. 2. Unusual vascular responses in the umbilical artery, mediated by endothelin-like receptors

    Författare :Maria Laursen; Urogynekologi och reproduktionsfarmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproduction; sexuality; Obstetrik; gynekologi; andrologi; sexualitet; andrology; gynaecology; Obstetrics; Medicin människa och djur ; Medicine human and vertebrates ; unusual vascular responses; endothelin-like receptors; human umbilical artery; reproduktion;

    Sammanfattning : In this present study the population of endothelin-like receptors in the human umbilical artery was examined in vitro in different parts of the umbilical cord. Immunohistochemistry revealed ETB receptors in the endothelium and an uneven distribution of ETA receptors in the smooth muscle of the arterial wall, when comparing different parts of the umbilical artery.

  5. 4. Audio spectrum analysis of umbilical artery Doppler ultrasound signals

    Författare :Ann Thuring; Lund Obstetrik och gynekologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The aim of this thesis was to develop an objective method for evaluation of umbilical artery circulation based on auditory perception of the Doppler sound signals. Study I. The operator listened to synthetically produced sound signals from continuous flow. LÄS MER

  7. 5. Effects of Delayed versus Early Cord Clamping on Healthy Term Infants

    Författare :Ola Andersson; Lena Hellström-Westas; Magnus Domellöf; Heike Rabe; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; active management; birth; breast feeding; cord clamping; ferritin; growth; haemoglobin; human infant; infections; iron; iron deficiency; iron deficiency anemia; iron status; morbidity; neurodevelopment; randomised controlled trial; umbilical cord; Pediatrik; Pediatrics;

    Sammanfattning : The aim of this thesis was to study maternal and infant effects of delayed cord clamping (≥180 seconds, DCC) compared to early (≤10 seconds, ECC) in a randomised controlled trial. Practice and guidelines regarding when to clamp the cord vary globally, and different meta-analyses have shown contradictory conclusions on benefits and disadvantages of DCC and ECC. LÄS MER
